This study proposes the design of a roll-to-roll system for flexible electronics that enables accurate and precise tension control. It analyzes the factors for change in the tension of a roll-to-roll system and develops a tension model for each section to successfully predict the tension that is applied to such a system, the sagging of film according to tension, and deformation due to residual stress. This series of modeling processes allow engineers to design a roll-to-roll system for flexible electronics. Both a velocity control method for the tension between in-feeder and out-feeder—where there is no change of roller radius—and torque control method for the tension in modules like the rewinder, where the roll radius changes, are proposed. A roll-to-roll system according to the proposed design procedure and tension control methods was manufactured and experimented on under various test conditions. The accuracy and precision of velocity control between the in-feeder and the out-feeder were 100.01% and 1.15%, respectively, whereas those of torque control between the out-feeder and the rewinder were 99.9% and 1.35%, respectively, both at one sigma. The experiments confirmed that the two proposed types of tension control methods were accurate and precise. The experimental result with a monitoring sensor showed that the modeling was valid and that an accurate roll-to-roll system minimizing tension reduction was built. This study successfully demonstrated roll-to-roll system design and control techniques that are applicable to various pieces of roll-to-roll process equipment.

这项研究提出了用于柔性电子设备的卷对卷系统的设计，该系统能够进行精确的张力控制。它分析了卷对卷系统张力变化的因素，并针对每个部分开发了张力模型，以成功预测应用于该系统的张力，根据张力产生的薄膜下垂以及由于变形引起的变形。残余应力。这一系列的建模过程使工程师能够设计用于柔性电子设备的卷对卷系统。提出了一种用于进纸器和出纸器之间的张力的速度控制方法（在其中辊半径不变的情况下）以及用于在诸如复卷机等模块中的张力（在其中辊半径发生变化的情况下）的转矩控制方法。根据所提出的设计程序和张力控制方法，制造了卷对卷系统，并在各种测试条件下进行了试验。进纸器和出纸器之间的速度控制精度和精度分别为100.01％和1.15％，而进纸器和复卷器之间的转矩控制精度分别为99.9％和1.35％。一个西格玛。实验证实，所提出的两种类型的张力控制方法是准确而精确的。带有监控传感器的实验结果表明，该建模是有效的，并且建立了将张力减小最小化的精确的卷对卷系统。这项研究成功地证明了适用于各种卷对卷工艺设备的卷对卷系统设计和控制技术。
